A North Otago dairy farm has been confirmed as being infected with Mycoplasma bovis.
MPI says the farm is connected to known Infected Properties (IPs) through stock movements and that tracing work from these farms is now underway.
In the same week, one more previously infected Southland farm had its IP status removed MPI said.
After the infected stock was depopulated, the farm completed its 60-day stand-down period during which it was cleaned and disinfected.
MPI reports that the Response Recovery team is now assisting the farm with returning to normal operation.
